For example, through much of the unirrigated temperate areas of the world, the "common earthworm" is actually Aporrectodea (= Allolobophora ) trapezoides , which in those areas is a similar size and dabk color to L. terrestris . Earthworm Ecology. Few earthworm species display all these characteristics, and in fact only five have been used extensively in vermicomposting .

These species produce ephemeral … To date, approximately 91 species of earthworm have been The bacterial species reported in the intestine of earthworm belong to bacillus,azotobacter, pseudomonas etc. The most diverse families of earthworm species in India are Megascolecidae comprises 153 species (119 native) of 15 genera; Octochaetidae with 130 species (129 native) of 29 genera and Moniligastridae with 83 species (all native) of 3 genera. In the world there are over 6,000 species of earthworms, classified in 20 different 'families'. Earthworm presence and activity can alter soil pH, which has a significant influence on Al toxicity.

There are many, many species of earthworm. It has red segments, and yellow intersegmental furrows. It was placed in a Petri dish with cotton wool soaked in chloroform and covered, until there were no more signs of movement. Anecic earthworm species include Aporrectodea longa, Aporrectodea nocturna, Lumbricus friendi and Lumbricus terrestris. Because of their narrow ecological plasticity to soil edaphic factors, members of the largest native genus Eutyphoeus can be considered as “stenoecious.” Various specialists report that certain species have the potential to live 4-8 years. AU - Zorn, M.I. AU - van Gestel, C.A.M. n., from Srinan National Park.After comparing with … Here we tested whether and to what extent the epigeic earthworms Eisenia andrei, Eisenia fetida and Perionyx excavatus, widely used in vermicomposting, are capable of altering the microbiological properties of fresh organic matter in the short-term.
